GHINb-GLEANING PROCESS.

A Application filed August 21, 1905. Serial No. 275,104.

. To all whom it may concern:

Be it known that I, J AMES PAss, citizen of the United States, residing at town of Geddes, in the county of Onondaga and State of'New York, have invented certain new and useful Im rovements in China-Cleaning Processes;-

declare the followin to be a am I do hereb (l exact description 0 the infull, clear, an

'vention, such as will enable others-skilled in containing a suitable har granular material, and rotating the case, whereby the ware is smoothed, scoured and cleaned from the adhering particles, rough edges, etc. -During the process, the dust formed is preferably exhausted by an air draft.

A desirable case, or rumble, for practicing my process is constructed of an open frame covered with wire cloth, forming a screen to retain the granular material but to permit the dust to sift out. The rumble may be inclosed in a closed box, from which the dust is A exhausted by means of a fan, or blower. A desirable construction of such machine, on which I propose to file an application, is shown in the drawing herewith.

Figure I is a vertical, longitudinal section of the inclosing box ShOWlIl the rumble artly in elevation and part y in section. ig. II is a vertical cross section. 1 In the fi ures, 1 indicates the case, or rumble, oarrie on shafts 2 in bearings, or standards, 3.

4 are the heads, or ends, of the rumble which may be solid; 5 are the side ribs with openings between; 6 are longitudinal wearing strips to assist in retaining the ware in position; 7 is the wire clothof sufficiently fine mesh to retain the granular material. A portion of the case is hinged at 8, forming a cover which is secured, when the rumble is filled, by suitable clamps, or hasps, 9.

10 are outside strips for securmg the Wire cloth. 4

11 is a removable partition 'to'divide the case into compartments where desirable.

'14'-is the closed box-having cover 15, and outlet 16, through which the dust is drawn out by fan 17 arranged'at any convenient lace 1n the building, and delivered out of the actory by pipe-18, chimneyor by any. desir-' able means.

19 indicates the china plates in the rotating rumble.

20 is the line shaft, 21 the pulley thereon,

23 the belt, 24 pulley on sha t 2 and 25 the idler-ordinary means for operating the rumble.

Heretofore, chinaware, etc., has universally been cleaned by hand, as with sand paper and brush, but this was slow, laborious, and not perfectly effective, as the articles were more or less unevenly cleaned, and left slightly rough. It. was also an unwholesome occupation.

I have discovered this new process by which, without breaking these brittle articles, a large number can be well cleaned in a short time, so as to be practically smooth and in the best condition to be glazed. This isdone with much fewer workmen and without danger to their health. In my process, the ware, plates for instance, are set on edge in the compartment, so that they have some movement of rotation, and are sufficiently spaced to admit the granular material between them, and yet not packed too loosely, whereby they might be broken. A suflicient amount of some suitable anular material is placed in the rumble, an acts more or less as a cushion, on which the plates rest -and strike as they roll. This material is also raised and poured over the plates, between which it passes during the rotation. Broken bisque is a sample of a desirable granular material.

I have referred to lates, but my rocess may be applied to hol ow ware, as wel to flat ware, an 1s very effective in cleaning the inside of hollow ware. My rumble may be cylindrical or s uare or of any suitable form, and with'any d esirable number of compartments.

Having thus described my invention, what tersPatent, is 2- 1. The herein described process of cleaning china ware, consisting in depositing a quantity of the articles to be cleaned in a suitable case so as partly to fill the case, but leav- I claim as new and desire to secure by Leting the articles a limited ran e of movement, de ositing a quantity of her 2. The herein described process of cleanin china were of various shapes and sizes, whic 1 consists in first baking the ware then depositin a q uantity of the articles, so baked and ung azed, in a suitable case,- depositing a quantity of broken bisque in ranular form in the case and-then rotating t e case.

3. The herein described process of cleaning china plates after baking and before glazing,

which consists in packing the lates on edge in a suitable rotatable case ut loosely so that they will remain substantially on the edge, and yet with suitable spaces between the respective plates and between the edges of the granular mate- 1 ria in the case and thenrotating the case-v eeaeee JAMES PASS.
